Abstract

A data communication emulating unit (18) in a user terminal (10) or a proxy device monitors communication between an application unit (16) in the user terminal and a proxy unit of the proxy device, which communication employs requests (REQ) and responses (RES) based on a data communication protocol. The data communication emulating unit then determines a communication pattern of the monitored communication, evaluates if the communication is efficient or not based on the communication pattern and changes communication strategy if the communication pattern is found to be inefficient. Change in strategy is performed through disrupting communication between the application unit and the proxy unit using the data communication protocol and instead ensuring that communication between the proxy unit and application unit is performed based on a signaling protocol via a signaling communication unit (20).

Generally speaking, the present invention relates to reduce the power consumption in the subscriber equipment when user terminal has applying unit, this applying unit uses the data communication protocol based on request-response, for example, and the client-server agreement.Advantageously, this agreement or according to the application layer protocol of osi model.This agreement can be HTML (Hypertext Markup Language) (http) and based on other agreements (such as hypertext secure transfer protocol (https)) or the agreement on it (for example, Simple Object Access Protocol (SOAP)) of http family.Yet, should be realized that, the invention is not restricted to this specific protocol, but can use with other agreements, for example APPC (APPC), BitTorrent and Data distributing (DDS).
The applying unit of carrying out this function can be the thin-client that basically only has data representation (presentation) ability, for example web browser.Yet it also can be the Fat Client with more multiprocessing ability.
In addition, applying unit can be the applying unit that uses any type of above-mentioned data communication protocol, it can use or utilize one or more other agreements, for example, asynchronous java script (AJAX), use based on the communication expanded of the bidirectional flow (BOSH) of synchronous HTTP and presentation protocol (XMPP) (namely based on BOSH XMPP), Comet, Bayeux and Pushlet.
Compunication and telecommunications merge just more and more.This is not only providing service and the function aspects relevant with compunication to have advantage to a lot of telecommunication users, and is providing telecommunications service and function aspects also to have superiority to the computer user.This is so that the user may use various types of terminals and network to obtain content from the server on the network such as the Internet.
Yet, be used for the evolution of the communication technology of accessed content more or less all based on computer, wherein, not have solution or fully do not solve the special circumstances of for example cellular communication and so on.
A kind of such special circumstances are problems that energy consumes.Because a lot of cellular devices are of portable form, it is usually battery-powered.There is restriction in battery aspect its power that can store.This means that for fear of too fast battery discharge communication must be efficient.
Compunication evolution aspect a lot, but do not consider the problem that this energy consumes.This means the unnecessary energy of the frequent use of communication that applying unit usage data communication protocol is carried out, perhaps in other words, consider the amount of the reality of the content that receives, it is usually highly unnecessary to obtain the required quantity of power of content.
The invention solves this situation.
Now the first modification of the present invention will be described in more detail in the non-limiting example context of two communication networks.Two networks 11 and 13 have been shown among Fig. 1.The first communication network 11 can be cellular network in this article, for example, and Universal Mobile Telecommunications System (UMTS) network or Long Term Evolution (LTE) network, and second communication network 13 can be computer communication network, for example, the Internet.

Fig. 4 schematically shows the structure of the agent equipment corresponding with the structure of user terminal among Fig. 2.There is the agent unit PU 30 that communicates by letter with the applying unit of user terminal via second communication interface CI 36 herein.In this article, agent unit is second data processing unit of communicating by letter with the first data processing unit in the user terminal.In this article, the second data communication interface 36 also be by agent unit 30 with the communicating by letter of the applying unit of user terminal in the socket set up.Therefore, the data protocol interface that the data communication protocol that this interface is with agent unit uses is associated.Therefore, agent unit 30 receives request REQ and sends response RES to these requests from applying unit via second communication interface 36.In fact, request REQ is intended to go to content providing, and the therefore corresponding request REQ ' of request REQ that arrives to the content providing send and receive in the second communication network 13 of agent unit 30, and and then receive response RES ', will respond RES ' as the applying unit that responds RES and be transmitted to user terminal.Similarly, be to carry out via the communication interface of socket form with communicating by letter of content providing.Yet, owing to the obvious reason that will become after a while, this is not illustrated among Fig. 3.In agent equipment, also exist 32, the second data communication simulation unit 32, the second data communication simulation unit to be connected to second communication interface 36, to monitor the data communication on this interface.The second data communication simulation unit 32 is also connected to the signaling communication unit, this signaling communication unit is used for using the entity communication of signaling protocol and network, be the form of the signaling communication server 34 herein, this signaling communication server 34 is carried out communicating by letter based on signaling with the signaling communications platform of user terminal.
The present invention is based on using the supervision of the communication between unit and the agent unit.For this reason, also be necessary in this article to be described in some general contents that (more specifically, in the request in this communication and in the response to these requests) provides in this communication.
Consider that below user terminal has the first address A1, considers that simultaneously agent equipment has the second address A2.As everyone knows, these addresses can be dynamic address.Yet also can use static address.These addresses can be Internet protocol (IP) address usually.

Should be appreciated that at this this request and response are only schematically illustrated in order to describe better the present invention.Payload and header can comprise much more data of various details forms.Yet, because this data the understanding of the present invention is inessential, with its omission.
Referring now to Fig. 1 that mentions before-6 and Fig. 7 and Fig. 8 the function according to a modification of the present invention is described, wherein Fig. 7 shows the flow chart of a plurality of method steps of carrying out in the general approach for reducing the power consumption in the user terminal, and Fig. 8 schematically shows the flow chart at a plurality of method steps that are used for carrying out in the general approach that this reduction is assisted.In this modification of the present invention, carry out the method for reducing power consumption in the first data communication simulation unit 18 in user terminal 10, and carry out the method for in this reduction, assisting in the second data communication simulation unit 32 in agent equipment 12.
When the user of user terminal 10 wants to use its applying unit 16 accessed contents that the content of equipment 14 is provided, begin to reduce the method for power consumption.The user begins the application that applying unit 16 is moving thus, and this application can be browser application.Under normal circumstances, by using the URL that is associated with content providing 14 to carry out access to the content in this application.Can obtain this URL by multiple different mode, for example use the search engine search, manually input or store as the collection in the applying unit 16 by the user.When the user provides URL or selected URL in applying unit to applying unit, thereby applying unit 16 is according to the request REQ of data communication protocol (being http) transmission to content herein, this data communication protocol is http herein, and for example it can also use AJAX, Bayeux, Comet or Pushlet.This request REQ sends to agent equipment 12 via the first communication interface 22, and wherein, this request REQ receives at second communication interface 36 places, and 30 forwardings from second communication interface 36 to agent unit.Agent unit is processed this request by IA interchange address and to content providing 14 Forward-reques REQ ', content providing 14 is processed this request, and transmission response RES ', response RES ' is received by agent unit 30, and be used as response RES and transmit to applying unit 16 via communication interface 22 and 36, this also carries out after changing the address.In this way, between applying unit 16 and content providing 14, exchange a plurality of responses via agent unit 30 or request is possible.Following situation is possible: usage data communication protocol sends the communication link of asking and responding and is held unlatching thereon, but does not exchange any message.This is not new equally.
In this article, the communication (step 38) that the communication pattern assessment element 24 of the first data communication simulation unit 18 monitors between applying unit 16 and the agent unit 30, in this example, this is to be undertaken by checking via the data of the first communication interface 22 exchanges, that is, by checking what applying unit 16 sockets relevant with this communication link that provide carried out.
Based on this communication that is monitored, thereby communication pattern assessment element 24 is determined the pattern (step 40) of communication according to the data communication protocol on the link between applying unit 16 and the agent unit 30.This can relate to determines how request and response occur regularly and/or study similitude between the request and the similitude between the response, that is, the request of transmission has seemingly heterogeneous to each other in communication, and respond have to each other seemingly heterogeneous.Then, communication pattern assessment element 24 is assessed the efficient (step 42) of communication based on communication pattern.If then communication pattern assessment element 24 determines that communication is (step 44) of poor efficiency, then judge and change communication strategy (step 48), if and communication pattern assessment element 24 determines that communication is efficient (step 44), then keeps communication strategy (step 46).In this case, keep communication strategy to comprise allowing applying unit 16 to continue to use these data communication protocols to continue to communicate by letter with agent unit 30 being exclusively used on the communication link of this session.
In this article, the change of communication strategy relates to the data communication (step 50) of this data communication protocol of use on the link that interrupts between applying unit and the agent unit, and enables communicate by letter (step 52) based on signaling with agent unit for it.This means, communication pattern assessment element 24 order data communication simulation elements 26 interrupt communicating by letter on the link between applying units and the agent unit, and tackle thus the data that provided in the first communication interface by applying unit 16, in the described data some or all are transmitted to signaling communications platform 20, so that so that this platform sends described data to the signaling communication server 34 of agent equipment.
In this article, the socket that data communication simulation element 26 is opened according to data communication protocol simulation connects, and with business from the applying unit pathfinding to signaling communications platform 20, to transmit based on signaling (for example, based on the IMS signaling).In order to carry out this pathfinding, signaling communications platform 20 is carried out the registration of the registering entities in the first communication network 11, for example, to the SIP registration of the IMS core of the first communication network 11, and in the change that then can inform to the second data communication simulation unit 32 in the agent equipment 12 communication strategy.This is informed and can comprise and inform communication pattern.
Therefore, the change of communication strategy can relate to the change of agent equipment 12 notification strategy.Yet this change also may be determined based on the communication on the supervision second communication interface in the second data communication simulation unit 32.If used notice, the second data communication simulation unit 32 is for example via based on the message of signaling protocol (for example, sip message) receive this notice (step 54), then agent equipment also changes operation (step 56) according to new communication strategy.In this article, this change on agent equipment 12 parts relates to the second data communication simulation unit 32 and interrupts communicate by letter (step 58) between agent units and the applying unit, and replaces via the signaling communication server 34 and carry out communicate by letter (step 60) based on signaling with applying unit.Yet, simultaneously, between agent unit 30 and content providing, keep the data communication (step 62) according to the communication pattern of usage data communication protocol.This means the data that interception is sent to applying unit by agent unit, and in the described data some or all are sent to applying unit via the second data communication simulation unit.This also means to send to content providing according to communication pattern asks REQ ' and receives response RES* from this equipment.Similarly, in this article, the second data communication simulation unit 32 usefulness signaling protocols are simulated the connection according to data communication protocol between agent unit 32 and the applying unit 16.If communication pattern is not known in the second data communication simulation unit, it can transmit all data by its interception.Yet, if it is by obtaining notice or oneself finding to know that communication pattern, the second data communication simulation unit may be limited to the data of simulating and connect the upper data that send.
According to the present invention, poll pattern/behavior that communication pattern assessment element testing is initiated from applying unit 16 according to data communication protocol.Then, the data communication simulation element switches to registration in the first communication system with the poll of the type, entrusts this announcement/subscription behavior to use based on the structure base communication of signaling, namely, use IMS as the carrier by the first communication network, rather than use the HTTP poll.
In this way, interrupted the communication of the power consumption on the link of usage data communication protocol, and replaced the communication of using based on signaling, it can relate to according to signaling protocol and sends message, for example, and sip message.In this way, only just executive communication or open communication link when actual needs transmits and receive data, this has significantly improved efficient.Communication between applying unit and the agent unit is maintained at minimum.By this measure, Internet resources have also been liberated.Do not keep special-purpose and connect, this with for the whole communication session between applying unit and the agent unit keeps being connected comparing, also the first communication network is used in permission more neatly.Simultaneously, applying unit and agent unit keep not knowing the change of communicating by letter.They think that they are communicated by letter according to data communication protocol to each other.This has the advantage that does not need to revise applying unit and agent unit.The present invention is worked to the application of any type of the usage data communication protocol in the application unit.Yet the actual data that send are to determine by the intelligent process in the first data communication simulation unit.
Now, can also make about communication pattern assessment element with reference to figure 9 and how can determine to communicate by letter efficiently or more more details of poor efficiency, Fig. 9 shows the flow chart of the method step of sketching the contours of a modification can determining efficient.This modification can be used when applying unit uses so-called long polling scheme.According to the polling scheme of this type, applying unit 16 sends request REQ, and then communication link is held open, although agent unit 30 or applying unit 16 do not have data to send for a long time.Abandon connection until applying unit or agent unit are judged end-of-dialogue and one of them, link all will be opened.According to this modification that is exclusively used in long polling scheme of the present invention, the communication that communication pattern assessment element 24 monitors via the first communication interface 22, and this link that existence has a low utilization rate grade detected.In this article, this can exist " keeping active " designator KAI to carry out (step 66) in the header HD of the request REQ that is sending " keeping active " field by the detection of pattern assessment unit.Then, based on the detection to this designator, communication pattern assessment element 24 starts timer (step 68).Afterwards, communication pattern assessment element is compared the value of timer with threshold value TH, and this threshold value can have suitable value, for example, and such as 60 seconds.Then, if the value of timer surpasses this threshold value (step 70), the communication then thought is (step 72) of poor efficiency, and interrupts in the manner described before the data communication of the usage data communication protocol on the link between applying unit and the agent unit 30 and enable communication based on signaling.Yet if do not surpass threshold value, whether 24 researchs of communication pattern assessment element receive response RES via the first communication interface 22.If receive this response within the time limit, the communication then thought is efficient (step 76), and stops timer.If detect new request, then can again start timer.Yet, if do not receive response, again study threshold value (step 70).In this way, might determine whether communication is efficient.
In this modification, will be switched to connection (being based in this article the connection of IMS) based on signaling according to the connection of data communication protocol.This means that the data communication simulation unit will simulate the data communication of data communication protocol in the socket rank, so that applying unit thinks that still communication link opens.Then, communication pattern assessment element will switch to the first data communication simulation unit to the connection according to the unlatching of the communication of data communication protocol, to set up the connection based on signaling protocol (being that IMS connects in this article) to the second data communication simulation unit.In the example of IMS and http, so the SIP that the first data communication simulation unit will use the signaling communications platform to carry out IMS network and the second data communication simulation unit registers.The second data communication simulation unit can use the signaling communication server 34 to carry out from data link to the switching via SIP that HTTP is connected based on the link of signaling, is retained to simultaneously the connection of content providing.Afterwards, the second data communication simulation unit abandons " directly " connection between agent unit and the applying unit.When content providing responds with content, then the second data communication simulation unit 32 can for example will send it back be used to the sip message of setting up IMS transmission connection via RSVP (RSVP) and hold substantial user terminal.Thereby can send undersized response with sip message.Now, comprise that all responses of new data and request all will come via the IMS transparent transmission, until no longer include long polling request by the virtual ims path between user terminal and the agent equipment.
Should be realized that the searching in the said method step " keeps active ", and designator is optional.As alternative, as long as can start timer just detect request.
It also is possible that applying unit, agent unit and content providing are used short polling scheme.In this case, the another way that needs the research communication pattern.In this short polling scheme, exist the some requests and the response that are sent out and usually in payload, have at least identical data.
In this case the supervision of communication related to communication pattern assessment element 24 detections the first request (step 78), and also relate to first response (step 80) that detects this request.Then, communication pattern assessment element 24 can local be stored in the copy of the destination identifier that occurs in the payload of request, and this destination identifier can be the URL of content providing.This identifier can be stored in the communication data memory 28.Communication pattern assessment element 24 also copies to the response data RD in the payload of the first response in the communication data memory 28 (step 82).Detect afterwards the second request (step 84), and then detect the second response (step 86).Then, the destination identifier that uses and the destination identifier of storing in this second request are compared (step 88), and if its difference (step 90), the communication then thought is efficient (step 92).Yet, if they are identical (steps 90), the response data of the second response and the response data RD in the communication data memory 28 are compared.If response data different (step 94), the communication then thought equally are efficient (steps 92).Yet if identical response data (step 94), the communication thought is (step 96) of poor efficiency.In this case, the again change of executive communication strategy.24 present order data communication simulation element 26 simulations of communication pattern assessment element are by the data communication in the connection of two communication interfaces realizations.This is to monitor that by the data communication simulation element request on the first communication interface carries out.If detect the request that equipment is provided to identical content, then do not send this request.For it, the data communication simulation element is obtained response data RD from the communication data memory, and comes application is responded (step 98) with the response data of this storage.
Yet different requests will be sent out.So, will send these different requests to signaling communications platform 20 by data communication simulation element 26, it 34 is transmitted from signaling communications platform 20 to signal server, with by 32 pathfindings of the second data communication simulation unit to second communication interface 36.
Therefore, the data communication simulation element comes response request with the response data of storage, and so that this response appear to and sent by the agent unit of agent equipment.Therefore, this is to carry out in the situation that does not exchange any request or response between user terminal and the agent equipment.Simultaneously, the second data communication simulation unit 32 can produce its oneself request, and this request appears to the request of the communication pattern that detects.Then, these requests are forwarded to agent unit, and these requests appear to and send from applying unit.Then, will be by known way 16 transmissions request corresponding with the request of the second data communication simulation unit 32 generations from agent unit 30 to content providing.Agent unit 30 also will receive response from content providing 16, then provide this response at second communication interface 36, be used for sending to the applying unit of user terminal.Yet these responses are not sent out, but are obtained by the second data communication simulation unit 32.If the response data of response is identical with the response data of using before, namely, if the response that receives from content providing has comprised the identical response data of response data of storing in the communication data memory with the first data communication simulation unit its payload, then do not send response from agent equipment to user terminal.Yet, if payload is different, the second data communication simulation unit sends response to the signaling communication server 20, the signaling communication server 20 sends this response to user terminal in sip message or in the file that SIP initiates transmits, the first data communication simulation element is obtained this response from the file transmission of sip message or SIP initiation, then provide it to the first communication interface of applying unit.Also mention herein, if the change of the notified communication strategy in the second data communication simulation unit, this notice can comprise above-mentioned response data or to the indication of this response data, and the destination identifier of content providing, for example, and URL.
About data communication protocol (it is http) and based on the agreement of signaling (namely, about the IMS use is SIP), can therefore find out, communication pattern assessment element is taken over all new short HTTP polling request with order data communication simulation element, and the response data pattern of simulation repetition.Simultaneously, the data communication simulation element also will be carried out the SIP registration to the IMS network, and order execution short poll in the second data communication simulation unit to substitute desired http response.If the second data communication simulation unit notices that response changes, then its IMS transmission that can open via RSVP connects, in order to return large HTTP content to user terminal, the HTTP content is less else if, then otherwise beams back content in sip message.
In this way, it is minimum that communication between applying unit and the agent unit keeps, thereby and saved energy, and at the same time, applying unit and agent unit think that all it communicates according to data communication protocol.In above-mentioned modification, the agent unit regular event namely, similarly is to exist directly between applying unit and the agent unit to connect.Should be realized that as alternative, agent unit can comprise the function of the second data communication simulation unit.Thereby agent unit can be the agent unit of " intelligence " more, and it keeps and being connected of content providing, and changes into simultaneously with user terminal and carries out communicating by letter based on signaling.
In this article, it should further be appreciated that, not necessarily will in user terminal, carry out the research of communication pattern.It can be carried out in agent equipment equally.Therefore, communication pattern assessment element can be provided in the communication equipment, and this communication equipment can be agent equipment or user terminal.This means that also the data communication simulation unit in user terminal or the agent equipment generally includes the data communication simulation element, and depend on whether communication pattern will be studied and comprise or do not comprise communication pattern assessment element, and also comprise alternatively the communication data memory.
The form of processor that can be by having the program storage that is associated advantageously provides communication pattern assessment element and the data communication simulation element of applying unit, signaling communications platform and the first data communication simulation unit, and this program storage comprises the computer program code for the function of carrying out these unit.Also can provide by identical mode agent unit, the second data communication simulation unit and the signaling communication server.Yet, this computer program code can be provided as the computer program on the server for example, then download to user terminal or agent equipment.
This computer program also can be provided on the computer readable device, for example, form with data medium, as carry CD ROM dish or the memory stick of this computer program with computer program code, in the time of in being loaded into user terminal or acting server, this computer program code will be realized the function of above-mentioned one or more unit.Schematically show such computer program among Figure 11, it is the form with CD ROM dish 102 of above-mentioned computer program 100.
Although think that in conjunction with current most realistic and preferred embodiment described the present invention, should be appreciated that to the invention is not restricted to the disclosed embodiments that on the contrary, the present invention is intended to cover various modifications and equivalent arrangements.Therefore, the present invention only is limited to the appended claims.
